I have to figure out a way to catch my pyramid butterflies ASAP. I used to think these things were reef safe but I guess their appetites can change when they mature and now that they have been in the tank for 3.5 years they've turned into little monsters! They are starting to cost me a fortune in LPS, zoas & clams.
In the past 3 weeks or so they have killed/eaten my bleeding apple scoly, pink tip elegance & Blue tip elegance colonies, countless zoas, wellsophyllia, 2 varieties of frogspawn colonies, 2x clams -a crocea & squamosa & my Aussie nuclear green prized hammer. There is probably more but that is all I can think of right now. I want to kill the little jerks! It looks like I'll need to invest in a fish trap.
Any other ideas?
